` Lette/rs Patent 87,724, dated Mor/rch 9, 18(159.

IMPROVEMENT IN CULTVATORS.

The Schedule referred to in these Letters Patent and making part of the same. I

v me- To 'all whom 'it ma/y concer/n:

Be it vknown that I, I).` O. STOVEIg, of Lanark, in the county of Carroll, and'State of Illinois, have invented a new and useful Improvement-in Oorn-Gultivators; and Ido hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled-in, the art to make and use the same, y reference being had tothe'accompanying drawings,

forming part of'tiiis specification. f

This invention relates to improvements 'in the construction of cultivators, the object'of which is to make them more-useful than as atpresent arranged. l v

It consists in the-v combination of the.A pivoted adjustable yoke with the bent rods, the brackets, and the ame ofthe carriage, whereby the plow-beams are connected to the carriage, as will be hereinafter more fully described.

Figure 1 represents a -sectional elevation of a cultivator, constructed according to my improvements, taken on the line a: x of iig. 2; and

` Figure 2 represents a plan view of the bottom of the same. Y

Similar letters of reference indicate like parts.

The cross-beams A of the frame are supported upon the inverted V-shaped brackets B, in the apex of which vthe axles of the wheels are supported.

O represents rods, bent at about their centres into right-angular form, and secured by one end to the brackets, and by the other to the lower face of the front beam A, forming the means for supporting the plow-beams.

.D represents metallic yokes, pivoted to the horizontal parts of the rods O, and to which the plow-beams are adjustably connected, as represented in red in g. 1, by bolts, or otherwise, so that the plow may be brought nearer to or further from the said yokes, to change the pitch of the plows, and admitting of the vertical oscillation of th plows, caused bythe irregularity of the ground.

The said yokes, being turned above this support, will have the effect, when it may happen that the wheels are turned backward, to raise the plows out of the ground to some eXtent,'and thereby admit the said backward movement, without damage to any part of the same..

This arrangement I consider an important feature, as itis often necessary to back up the 'plows to disengage them from roots, and for other causes, which has been attended with danger to the machines, as heretofore constructed, on account of the tendency of the vplows to be4 forced deeper into the ground.`

l Having thus described my invention,

I claim as new, and desirel tosecure by Letters Patent- The 4combination of the pivoted adjustable yoke D with the bent rod C, bracket B, and carriage A, arranged and 'operating as described, for the purpose specied.

The above'specication of my invention signed by.

me, this 14th day of September, '1868.
